Frequently Asked Questions
Wet-back designs eliminate the need for a rear refractory wall, reducing maintenance costs and improving heat absorption efficiency by keeping the combustion chamber surrounded by water.
The finned tube economizer captures waste heat from the outgoing flue gases and uses it to pre-heat the feed water, significantly lowering the amount of fuel required to reach boiling point.
Yes, the WNS series is designed for versatility. Depending on the burner configuration selected, it can operate on natural gas or diesel oil to provide flexible energy sourcing.
Corrugated tubes increase the turbulence of the hot gases for better heat transfer and provide the flexibility needed to absorb thermal expansion, preventing mechanical stress and leaks.
While it varies by water quality, we recommend quarterly burner inspections and annual internal descaling to maintain the peak efficiency ratings of 92% or higher.
Absolutely. By using international brand burners and high-grade fire-proof insulation, our boilers are engineered to meet rigorous industrial safety and pressure vessel standards.
